There are a number of i18n messages in the Cite extension that don't seem to be actually localized. See below. It seems it is better to eliminate these messages - I especially don't see a reason to let HTML structures be localized. In Parsoid land, we are relying on CSS to get different formatting and localization of citations. Eliminating unused customizations could simplify the CSS rules that need to be written and maintained in some cases.
